|Title:||Hole Burning Observation In Spontaneous Emission Spectra From 1.3 μm Ingaasp/inp Laser By Using External Light Excitations|
|Abstract:||Spontaneous emission spectra from 1.3 μm InGaAsP/InP double-heterostructure (DH) laser with quaternary confining layers was observed. A new experimental result is presented in this paper showing that spectral hole burning just below the current threshold may occur due to external light excitation. These experimental observations can be explained with a theory developed by Yamanishi and co-workers relating spectral hole burning to saturation of intervalence band absorption. Due to the appearance of hole burning by external light excitation, some confusing interpretations that appeared in the recent literature may now be cleared. © 1984.|
